Also in development by Time Donkey designer Steve Swink and Scott Anderson — and playing somewhat like Tyler Glaiel’s Closure in reverse — Shadow Physics sees you controlling a character locked on a flat 2D shadow plane while you simultaneously manipulate a light source to cast shadow platforms necessary to proceed.

As you can hear in the video, the demo’s a rough cut with ideas still not implemented, including variable light brightness that can wash out shadows in certain areas to create gaps in platforms, and colored lights for colored shadows, each with unique properties.

This early on there’s no set date or target platform, but Anderson says the game will be in development for at least another year.
